1.2311(40crmov7) has no corresponding domestic brand material.
1.2311(40crmov7) steel is produced by "ultra-pure" process. After pre-hardening, it is generally used as plastic die steel, showing high micro-purity, excellent uniform structure and excellent polishing and lithography performance. After heat treatment, it has good mechanical processing and polishing properties, can be nitrided, and is suitable for surface treatment such as chromium plating, with uniform hardness (thickness up to 400mm), good toughness and good machinability. The gold structure is martensite and bainite.
The chemical composition of1.2311(40crmov7) is as follows:
